【High-quality material】The toilet seat hinge clip is made of rubber and stainless steel. The rubber is more resistant to dirt, wear, and tear, and is less likely to break. Under the protection of the rubber, the metal screws are less likely to rust and are durable. 【Easy to install】The rubber washers have threaded parts, so you only need to insert them into the holes on top of the toilet. When you tighten the screw, it expands and sinks into the hole, eliminating the need to screw the other end of the screw. 【Hinge plate】The round hinge plate can make these toilet hole screws more stable. When tightening the screw while the washer is pushed into the hole, be careful not to overtighten the screw, as it will sink into the washer. Wide Application: Robust, reliable, and solid mounting kit, specially designed for toilet support brackets. The toilet seat accessory fits some standard hinged toilet seats (14-15 mm toilet seat hole), making it convenient and time-saving. 【Package Contents】
